I have run into a problem that appears to be related to multiple profiles
maching the logon I pass in via CDO. I presume this is related to the Show
Dialogue switch on CDO logon.

An example here would be that I have two accounts with similar names. The
alias of account 1 is "testuser" account 2 is "testuser2". When I pass in the
following;

objsession.Logon "","",false,true,true,true,servername,"testuse r"
I get back;

The information store could not be opened MAPI_E_LOGON_FAILED

If I pass in
objsession.Logon "","",false,true,true,true,servername,"testuse r2"
It works because is has resolved the profile without multiple returns.

How do I tell CDO logon that the alias I am passing in it absolute?
